No.... the original nes slot was defective and that's why it wore out so quickly. The nes 2 and clones use the corrected slot, which is just as durable as more modern cart slots. Regardless, the super joys have famicom slots, not nes slots, which never had such an issue. Besides, if you are running american games then you'll be plugging into an adaptor plugged into the slot, so the wear would be on your 5-15 dollar adaptor and not the actual slot.
